Myv present invention relates to laundry driers particularly adapted for domestic use. It is the principal object of my invention to simplify and improve existing types of such driers to increase the efliciency of same. More specifically, it isan objeot'of the invention to provide a laundry drier for domestic use utilizing low pressure steam, as for example that `used in they heating systems of apartment houses. Further objects to be attained and advantages of the invention will be apparent as the description proceeds and the novel features will be pointed out in the claims.

'I'he invention will be best understood by reference to the following detailed description taken with the annexed drawings, in which Figure 1 is a view in vertical longitudinal section of a preferred embodiment;

Figure 2 is an end elevational view as seen to the right of Figure l; and

Figure 3 is a section taken on the line 3 3 of Figure 1.

Referring to Figure 1, I0 denotes generally a clothes supporting rack consisting of horizontally disposed rods Il, I2, I3, I4, etc., which extend from a perforate rear framework I8 to an imperforate front wall I8a. As seen best in Figures 2 and 3, the frame is preferably not very wide in relation to its height or depth so as to permit ready access to the rods, thereby facilitating the putting in and taking out of the clothes. 'I'he racks l0 are contained within a housing I9 from which the racks may be drawn out to the position shown in dotted lines in Figure ,1. To permit this, the following arrangement of parts may be provided: Supported in said housing is a pair of channel beams 2U, 20, one support for which, 2l, is shown to the right of Figure l. Journaled in said supports 2l is a grooved roll 22. In the groove of this roll rides a rail 23 from which the rack is supported by means of a tie member 24, at the right of vFigure 1, and a bracket 25 at the left thereof. At the junction of the bracket 25 and the rail 23 is journaled a pair of rolls 2S which travel within the channel beams 20, 20. Bracket 25, by virtue of its horizontal displacement to the left of the rack I 0, Figure l., provides sufiicient leverage to support the rack in its drawn-out position in which the rolls 26 approach the grooved roller 22. y

Bracket 25 is attached to framework I8 by means of bolts 30 and 3l, Figure 3, there being provided vfor the latter a platev32, attached to framework I8,r having intersecting a slot 33 by means of which the framework can be accurately suspended by means of bolt 34.

(Cl. 34-40) i 1 A localized source of heat is provided preferably in the form of a steam coil 35 connected with a source of steam, not shown, the coils preferably being provided with iins 36 for increasing radia- F tion. Beneath the coil 35 is disposed a fan 37 5 driven by a motor 38, asuitable 'casing 4U being provided around the fan and coil to prevent air slippage from the fan and to direct the'air over the coil. The inlet side of the fan communicates with air duct 42 for the recirculated air through the apertured support 43. Said inlet also communicates with the outside atmosphere through aperture 44 provided with a slide 45 by means of which the volume of fresh air admitted may be regulated.

It is a feature of the invention to distribute the air more or less uniformly over the clothes and to this end a baille 4l is provided having apertures 48, Figures 1 and 3, at spaced intervals to direct the air in somewhat horizontal streams. Saidbaffle is also inclined or otherwise disposed so as to provide with the walls of the chamber a conduit having a decreased cross section as the distance from the coil 35 increases so as to assist in maintaining a uniform air supply throughout the drying compartment. The air thus set in circulation passes over the clothes to be dried in streams apportioned to the zones defined by the rods I I, etc., and more or less parallel to the plane of the clothes whereby a maximum surface of the clothes is presented to the air stream and circulation of the air is facilitated. The air is co1- lected in the down draught space 50 rearward of the rack ID, some of the air passing downwardly through the screen 5I at the bottom of the rack. A portion of the air is permitted toescape from the chamber through perforate frame I8 to a perforated pipe 55, the withdrawn air being made up by fresh air admitted through the apertured plate 44. When the clothes are dried the rack is withdrawn by pulling same outwardly by means of the handle 51 to the position shown in dotted lines in Figure 1, whereupon the dried clothes are removed and, if desired, a new batch of wet clothes is again hung on the rack. 45

It will be noted that by re-using the heated air until it is saturated with water vapor, a maximum utilization of the heat results. Furthermore, by leading the air in streams more or less parallel to the plane of the clothes, a minimum of resistance to the air flow takes place while affording ample contact with the clothes. By virtue of the improved construction, steam at a low pressure, as for example under ten pounds, may be used.

Various changes may be made in the embodiments specically described in detail without de parting from the spirit of my invention or the scope of the appended claims. Especially may the means for holding the clothes be varied while preserving the principle of drying herein set forth.

I claim:

1. A laundry drier having a rack containing a plurality of substantially horizontallydisposed clothes supporting members, a Yhousing therefor, said rack being capable of being moved to a withdrawn position from said housing but constituting therewith in closed position a substantially closed chamber, a localized seurcfepfy heat comprising a steam coil at the front end of said housing and disposed adjacent the bottom thereof, a fan for circulating air upward through the coil and a substantially Vupright baille carried by the front end of said lrack and disposed directly over said coil when said -rack is closed, said ,baille serving fordirecting the air lso heated from the coil and apportioning same to zones defined by said'clothes `supports .andrin vertical planes parallel with said supports, .and

said housing having a foraminous vfalse bottom acting to direct at `least ,a portion of the ,moisture laden air downward, whence it nds .its Way forward beneath said .false `bottom toward said heater and fan for recirculation,V means for 'venting at least a portion of the Vapor laden air,

nsource, thereby heating and creating an upward -streamvof said air, and an upright, inclined, ap-

ertured baille carried by said rack for directing the air fso heated from said source and for causing `a diiferential apportionment of same to zones defined by said clothes supports and in vertical planes parallel with said supports, and means for returning at leastL a .portion -of theair :for

recirculation by said blower`.means,means for f venting at least a portion of the vapor laden nair., and a means for admitting fresh air. A' 3. The ,driery according to claim 2 yincluding means for regulating the amount of fresh ;air added.
